The invention discloses an efficient cooling
grinding wheel applied to
ultrasonic machining, and relates to the technical field of ultrasonic auxiliary
grinding machining tools, the efficient cooling
grinding wheel comprises an upper ultrasonic
grinding wheel base rod and a lower ultrasonic
grinding wheel grinding head, and the ultrasonic
grinding wheel base rod and the ultrasonic grinding wheel grinding head are of an integrated structure; the interior of the ultrasonic grinding wheel base rod is hollow and extends to the bottom of the ultrasonic grinding wheel grinding head without penetrating, the interior of the ultrasonic grinding wheel base rod is in threaded connection or
interference fit with a sleeve, the interior of the sleeve is hollow and serves as a main cooling liquid flow channel, the
diameter of the interior of the sleeve is the main cooling liquid flow channel, and the
diameter of the main flow channel can be changed; a plurality of round holes are formed in the grinding wheel grinding head to serve as cooling liquid flow channels of the grinding head, inlets of the cooling liquid flow channels of the grinding head are connected with the
tail end of the main cooling liquid flow channel, outlets of the cooling liquid flow channels of the grinding head are located at the
machining position in the
grinding process, and cooling liquid grooves are machined in the cooling liquid outlets of the grinding head. And inner cavities of the main cooling liquid flow channel and the grinding
head cooling liquid flow channel are provided with
rifling structures with variable screw pitches and
variable number.
